Google is a search engine for human readable content. Shodan does the same for machine readable content.
You can:
- search for specific IP addresses, and it will show you the active ports, and running services.
- search for a specific response header in the set of countries
- browse through the screenshots of open VNC & RDP
- open webcams
- and more…
The free accounts can use any feature, but the list of results is limited. But if you really want to look under the deck of the internet, the subscription is worth it.
That’s cool AF. Shodan shows lots of cool things that I don’t think anybody minds being seen, but it also gives search results that could be used nefariously. It’s probably the coolest and creepiest tech product I’ve ever seen.
